Measuring Displacement on a Testing Machine: Pairing with Load and Surviving a Million Cycles
Displacement measurement on a testing machine is not the same as on a production machine. What is wanted is a zero that is still in place after hundreds of thousands of cycles, and a displacement value that can be matched to a load value at every instant. This covers the three hard requirements, why synchronisation with load matters more than accuracy, and the four places that actually give trouble over long cycling.
